Distinguish between plane polarized, circularly polarized and elliptically polarized light How can circularly and elliptically polarized lights be produced? Explain briefly how will you determine whether a beam of light is unpolarized, plane polarized, circularly polarized or elliptically polarized.
Find the values of Cp and ᵞ for a gas whose gas
constant is 0.324 kJ/kg K and Cv = 0 84 kJ/kg K.
If 2.25 kg of this gas with an initial volume of
1.15 m3 undergoes a process during which its
pressure remains constant at 7 bar and its
temperature becomes 280‘C at the end of the
process, calculate: (a) the change in internal
energy, (b) the change in enthalpy, (c) the
transferred heat, and (d) the work done.
